问题补充：
All her time experiments, she has no time for films.
A. devoted to do
B. is devoted to doing
C. devoted to doing
D. is devoted to do
答案：
A. devoted to do
B. is devoted to doing
(答案→)C. devoted to doing
D. is devoted to do
解析：句意：她把她的一生都贡献给了实验，没有时间去看电影。这里逗号后是句子，整个句子没有连词，逗号前不是句子，它是独立主格结构，这里是devote all her time to doing把一生贡献给做某事。所以all her time与devote应该是被动关系，故选C。
